6 Claims, No Drawings 1 ANIMAL FEED AND PROCESS CROSS REFERENCE TO RELATED APPLICATIONS This application is related to copending U.S. application Ser. No. 138,278, filed Apr. 28, 1971, now abandoned which discloses compounds of the Formula 1 and methods for their preparation.
BRIEF SUMMARY OF THE INVENTION DETAILED DESCRIPTION It has been found in recent years that meat-producing animals will gain more weight and gain it faster when various classes of compounds such as vitamins, minerals, estrogens, antibiotics, and tranquilizers are added to the diet. Although the presently available compounds are useful, new materials are still being sought that would produce weight gains more rapidly, to a greater extent, more efficiently with respect to feed intake at a lower cost and without undesirable side effects.
It is now possible by use of the present invention to obtain unexpected results in the feeding of meatproducing, milk-producing, or egg-laying animals; that is to say, an increased rate of weight gain, an increased amount of weight gain, an increase in milk production, or increased rate of egg laying, as well as increased feed efficiency, can be obtained by the addition of minute quantities of a compound of the Formula 1 to the animals usual nutrient feed.
Compounds of the Formula 1 can be prepared by .methods disclosed in U.S. application Ser. No.
138,278, filed Apr. 28, 1971, now abandoned.
Unless otherwise specified, all percentages are given on a weight-to-weight basis. The pound (1b.) weights given are avoirdupois units.
Feeding of the compositions of the present invention can commence for birds shortly after hatching and in the case of mammals, during the creep-feeding period of suckling animals when they are starting on solid food and, of course, after weaning. Feeding of the compositions is continued throughout the growing period, lactation period, or egg-laying period.
The total concentration of the compound of the Formula l in the feed composition is determined with re gard to the species of animal, age, weight, and average amount of feed consumed daily. Preferably the compound of the Formula 1 is employed in the finished feed that will supply the animal with a daily intake of from about 0.015 mg. to about 250 mg. per head per day.
The following table illustrates the range of compound of Formula 1 in milligrams daily dose per head per day for representative animals.
Range Preferred Animal Daily Dose/Head, mg. Daily Dose, mg.
Swine (birth to 8 weeks) 0.125 12.5 0.7 Swine (40 to 2001bs.) 0.775 72.5 4.0 Chickens (growing 0-8 weeks) 0.015 1.5 0.1 Hens (laying) 0.03 3.0 0.15 Turkeys (growing O-24 Weeks) 0.1 5.0 0.25 Beef Cattle (fattening) 2.5 250 14.0 Calves (012 weeks) 03 30 1.5 Dairy Cattle (lactation) 2.5 250 14.0 Lambs (fattening) 0.19 19' 1.0
The foregoing dosage can generally be accomplished by providing from about mg. to about 12,500 mg. of a compound of the Formula 1 per ton of finished feed.
Advantageously a compound of the Formula 1 is supplied in the form of a liquid or solid premix wherein the concentration is 2,000 times greater than the desired final concentration of the feed. For example, the compound of Formula 1 can be dissolved or suspended in a fluid vehicle such as corn oil, cottonseed oil, molasses, distillers solubles and the like to prepare a fluid premix. Alternatively, a solid premix can be prepared by mixing a compound of the Formula 1 with an edible solid diluent such as sucrose, lactose, starch, corn meal, flour, calcium carbonate, soybean meal and the like.
